What You Need First

Building and Reviewing a Custom App

Browse the API Reference and the Demos sections to familarize yourself with the phone API.

Write your phone app in JavaScript.

Write your app.json file, ensuring it has all the required information.

Zip your app's JavaScript file and app.json file together, naming the zip file in a way that helps you remember what the app does. If your app uses any images or language files, put them in this zip file also.
